(nautical) the point through which the resultant of all buoyant forces on an immersed hull are assumed to act; the centre of mass of the displaced water.

Alternative spelling of call center

(British spelling, Canadian spelling) Standard spelling of center stage.

(Britain) Alternative spelling of dead center

(chemistry) An atom having a spatial arrangement of ligands which is not superposable on its mirror image

(aeronautics) That point on an aircraft where all the various lifting forces act. If the centre or lift is not coincident with the centre of gravity on the fore/aft axis, the plane will pitch, if not coincident on the lateral axis, it will roll.

(mechanics) The point where a shear force can act without producing any twist in the section. In general not the centroid, but a point through which a force transverse to the axis of a beam section can act and not cause any twisting of the beam section.

(rare, dated) The centre of mass.

(mathematics, physics) A point, near, or within a body at which the object's mass can be assumed to be concentrated; it coincides with the centroid for a body of uniform density, and with the centre of gravity in a uniform gravitational field.

(rugby) A player who is positioned between the inside centre and the right wing
